Application August 12, 1,935, serial No. 35,738 3 claims. (cl. 257-125) This invention relates to a radiator having two separate cores vand two headers, each header having a transverse partition forming two compartments therein and the entire assembly formed in a unitary structure. One of said cores is adapted to cool the jacket liquid of an internal combustion engine and the other core being adapted to cool the compressed air from a compressor receiving its power from the engine.

An objectof my invention is to provide a dual purpose unit radiator which has a neat and conventional appearance and is suitable for mounting similar to radiators used for cooling the engine u liquid only. y

A further object of the present invention is to provide detachable cores, each of which mayy consist of a number of core units.

Another object of my invention is to provide two closely spaced transverse partition walls in vthe headers, forming two header chambers, the space between the two walls having permanent openings through the rear walls of the headers, whereby when the unit is immersed in liquid and air pressure is used for testing, if there is a leak in either wall, air bubbles will appear through the permanent openings. Further, if a. leak should develop after the radiator is placed in service, it would be readily detected because of the 'permanent openings, whereas a leak in a single transverse wall would at any time be difficult to detect, particularly so after the device had been placed in service.

To these and other useful ends my invention consists in matter hereinafter set forth and claimed and shown in the accompanying drawing in which:

Figure 1 is a rear elevation of my improved radiator indicating a conventional fan shroud and other parts common to radiators of the class. l

Figure 2 is a transverse section of the upper g header taken on line 2--2 of Figure 1.

Figure 3 is a horizontal fractionalsection of the top header taken on line 3-3 of Figure 2.

As thus illustrated the top header is designated by numeral I0 and the bottom header by numeral II. These headers are held in spaced relation by substantial side housing members I2|2, thus forming a unitary frame to which the usual fan shroud I3 may be attached.

Header I0 is, at its bottom, provided with a depending portion I4, thus supplying a face I5 which may be machined to provide a suitable gasket surface. vThis face y I5 extends preferably for the length of the header and is provided with a row of openings IB. A number of lugs I1 are openings provided which are drilled and tapped as indi- 4 cated by dotted lines in Figure 2. The purpose 1 units; each in their entirety designated by referl5 ence character A.

'Ihese cores A.. are adapted to beserved by the short header compartment as indicated by dotted lines in Figure 1. The other core units, designated in their entirety by reference character B, are 20 adapted to be served by the long compartments. Each core unit comprises a suitable number of nned tubes, the ends of the tubes having a suitable operating connection to core headers 25. Each core header has a suitable chamber which 25 is provided with openings which register with I 6, and also an opening through a suitable sleeve which vregisters with the threaded openings in lugs I1. I provide -a suitablecap screw 26 and a gasketv 21, whereby the headers 30 may be removably secured and sealed to face I5, the gasketA having openings which 'register with openings IE, whereby the coolant may pass from one header to the other.

Header Il, is similar to header I0, except in 35 minor details.

Thus when the units A are securely attached vto headers I0 and I I the engine the long chambers of each header exactly as cores 50 A are connected to the short chambers. 'I'he usual compressor served by applicants device, is provided with two outlets. I provide two inlets 33 and 34 to which vthe compressor outlets may be connected; thus lthe heated compressed air 55 Clearly, units A may be made into a single core of twice the width and units B may conceivably be made into fewer cores or in one core only. I prefer however to make use of the design shown but it will be understood,that various sized units and any number of cores and of any suitable capacity or ratio may be used and that many detail changes in the shape of the elements may be made without departing from the spirit and scope of this invention as recited in the appended claims.

Having thus shown and described my invention I claim:

l. A radiator of the class described, comprising two headers each having transverse partitions comprising two closely spaced walls having an outlet therebetween through the walls of said headers, said partitions being positioned to provide a long and a, short compartment in each header, means between the ends of said headers to thereby form a unitary frame, two or more narrow cores each comprising headers and a number of tubes and a multiplicity of closely spaced fins through which said tubes extend, said core headers having removable operating connections to said short compartments, three or more narrow cores each comprising headers and a number of tubes and a multiplicity of closely spaced tins through which said tubes extend, said last headers having removable operating connections with said long compartments.

2. A radiator of the class described, comprising two headers each having transverse partitions to thereby providel two compartments, said partitions comprising two closely spaced transverse walls having an outlet therebetween through the walls of said headers, means between the ends of said headers to thereby form a unitary frame, a core'comprising headers, a number of tubes and a multiplicity of closely spaced fins through which said tubes extend, said core headers having detachable operating connections to corresponding compartments in said headers, a second. core comprising headers, a number of tubes and a multiplicity of closely spaced ns through which said tubes extend, said second core headers having detachable operating connections to the other compartments in said headers.

3. A heat transfer device of the class described,

comprising an upper and a lower header having means between their ends to thereby form a frame, said headers having two closely spaced transverse partition walls forming two compartments in said headers and narrow transverse spaces therebetween, said narrow spaces having outlets through the walls of said headers, a core comprising tubes and fins having operating connections to corresponding compartments in said headers, a second core comprising tubes and fins having operating connections to the other compartments of said headers, said partition walls converging at a point near the inner walls of said headers forming a single narrow thin wall between said header compartments whereby the adjacent openings to said cores may be closely spaced.
